A few questions

Hey guys, I just got the unit and I think it is awesome.

I have a few questions or remarks so if you couol kindly take the time

My unit has the Freescale I.MX53 cpu 512 mb DDR3 ram

Runs android 2.3.7

MCU

2.11.1-1-10-1

System version 2.20.21

DVD

2.13.11-1200wb

1. Can someone point me to the latestest MCU for my unit along with the instructions on how to update it.

Is the update worth it? What does it do?

2.I think the iPod app is horrible, is there a better one out there? My main grip is that when I choose "artist" it justs lists songs in alphabetical order instead of the "album" order.

3. What is the best launcher to use with our head unit? I downloaded a random one that the play store suggested and it kept crashing Sygic.

4. My car logo is not in the logo settings, can someone point me to a tutorial on how to make one and upload it properly?

5. I hate the dancing droid boot up animation, how do I change it? Or can I eliminate it completely?

6. How do I root this? Can someone point me to the instructions please?

7. Can this unit be bricked? Or is it like an iPhone/iPad where it has a killswitch when things go wrong and just reboots?

8. I know my chances are slim to get an answer on this bit I have a 2007 chrysler 300, and I fit the radio in my dash, however the trim ring was not big enough, and now I have this gap between my dash and my head unit, I tried filing the supplied trim ring down down but the knobs where just in the way and would not turn properly and not to mention how ugly it looked.

Thanks in advance for your help, I would have looked this up myself, but there are 200+ pages and waaaaay too many posts.
[Android Head-Units] KID52:
Seems like a coincidence. Do you think they wrote the Windows decryption system into the Android unit? It's unlikely.

Chances are the encryption they use is weak, and can easily be cracked. It's just a case of knowing where to begin. For all we know, it could be something as stupid as a shift cypher using the file name as the key...
[Android Head-Units] Orisai:
Android doesn't have NTFS support, let alone EFS which is built on top of Microsoft's filesystem, but it's capable of using the same cypher algorithms as EFS (AES, SHA, DES) though. The only thing Android needs to be able to decrypt them during the upgrade process, is the manufacturer's or firmware developer's public key, which I believe is stored among the system root certificates.

This, providing EFS or a compatible file encryption mechanism was used to encrypt those files.
[Android Head-Units] KID52:
I think my post was misinterpreted given your response. Reading it again, I can see why.

Also just to add, the other update file I received did not have the green-coloured file names.

But yes, I agree with your response. I think we have a better chance waiting for the factory to release a decrypted version than figuring out how it is actually encrypted, let alone decrypting it ourselves. In other words, no root or customization for us :(

It is a shame, given the hardware improvements, this unit had a lot of potential.

In general I think the unit will sell, people who want it for what it is will buy it, but I cannot see anyone upgrading from the 2.3 unit.
[Android Head-Units] tin2001:
Is there a link around for these encrypted files? Sounds like an odd one which got my attention.
[Android Head-Units] sciallo:
1: No your MCU is newer than any available, and there isn't any noticeable changes anyway. In fact I would not even put MCU file on the card when flashing to root (see 6)

2: Can't help you, I don't do I-crap, but no there isn't any other that will interface with the hardware. just get a however-big solid state 2.5 hard drive and put your music there then you can use real apps like poweramp or whatever... There is also a bunch of apps that will let you sink your music with your computer

3: I love ADW launcher, but I haven't tried using sygic with it yet, not sure I want to use sygic at all. but that's just me (anyone else?)

4: in this huge thread starting at post #715 with post #1222 being the key one

5: It's a regular bootanimation as any other android device, there was some discussion on that here, but really a bit off-topic. there is plenty of other places that will tell you all about it. The short answer in my opinion is use one of the many apps available for it (of course root is needed) I used the utility in ROMtoolbox for it succesfully.

6: Get a rooted rom, i believe the latest is on post #1969, I don't think anyone has posted that update anywhere else, HAL9K likes to keep stats on downloads. You'll need to subscribe to a russian forum website, translation works pretty well on chrome browser, when registering the answer to the captcha is simply the sum of the two numbers, no need to figure out the russian characters) if you're too lazy for that, the next choice is post #920 ...again, I would remove the MCU file as your MCU is newer.

7: same post as the latest rom #1969. I believe I am the ONLY ONE who managed to hose it's unit irreparably, so it might just be a defective one. I have seen all kids of scares here, but they were all fixed by resetting wiping or reflashing. see my suggestions on post #2018

8: Nice yours came with a trim ring... I haven't crossed that bridge yet. looks like I'm not going to anytime soon :( anyone?

A shame it is... Not sure it will sell as well as it could... And some will get returned because of some silly expectation as we've seen early on with the 2.3 (granted those expectations are now met thanks to to community efforts)...

Post #1966 Is the link to one, the second one hasn't been released... I'd like to see the second one too.

There seems to be one more file in there, little tiny file could be a key. also as far as the hash, note that only the beginning of the file changes from file to file...

BTW [MENTION=1915855]KID52[/MENTION] should we start a new thread for the 4.1? you should be the OP

I would subscribe :)
[Android Head-Units] KID52:
I'm uploading the other update files I have, and will post them later.

Good idea on the thread, keeps everything together regarding that one unit so no one gets confused.

Please keep all discussion for the new Android 4.1 unit in the thread linked below.

I started a page here: http://xdaforums.com/wiki/Generic_Android_Head_Unit

Haven't had time to actually put content, and I don't think anyone else has either. Feel free to edit in any info you know of, particularly model names/numbers and how to identify them.
[Android Head-Units] G2k0:
Thanks. I had looked at very quickly and noticed the discussion was on the s150. We def need to beef that up a bit because this thread is just getting out of control. Cool I'll start adding some stuff.

@ ouku users - seen several variants of the rooted fw. Might be a good idea to gather some info on that. If anyone has upgraded recently please share :) Thanks

[Android Head-Units] sciallo:
I slacked too in that department... So far I have a handwritten list of post numbers with key topics I will use to get some content going. I think the Idea is to keep the existing page as a general description tips and how to tell them apart for all of them, we should have 3 subpages, one for the OUKU, one for the s150 and one for the newer 4.1 models.

The most recent rom was linked in post #1969, it still lives in the russian forum system 2.20.21
[Android Head-Units] adit9989:
Just a remainder, for S150 units, owners, the discussion is moved here: http://xdaforums.com/showthread.php?t=2503964 ; Please post any S150 related stuff there, and keep this thread for OUKU owners. I know, there is a lot of older info in this thread also, but it's to messy.

Wiki Update

Thanks tin! :) I added some info (whatever I know at least). I added a new section on modding which talks about how to add a custom bootlogo and bootanimation (two subjects I've seen kicked around a few times). Has anyone tried using Framaroot on a vanilla OUKU firmware? Will that work?

[MENTION=1071793]adit9989[/MENTION] Yes I am aware of that. Thanks. At first glance I thought the page tin started was for S150 devices only. I have an OUKU so I added whatever relevent info I know of to that page.

[MENTION=3081576]sciallo[/MENTION] - Thanks. I'm running an older version that Hal9k's had posted and after about 7 months or so with no major issues, I'm noticing the unit is stating to slow down a bit, on occasion will get stuck in a boot animation loop and so on. At this point I'm considering just downloading the latest version (from an FTP site Peter Chan had given me a while back). What sucks about getting Hal9k's fw is that you have to register on that forum (not that I mind, its just way too much work to be bouncing around from site to site to find the latest release and so on). Thats why I made my suggestion above to kind of centralize all the info needed, setup a fw repo (or links) and so on. Btw some a few pages back had posted another custom brew from these guys. http://www.ft86club.com/forums/showpost.php?p=1107961&postcount=1013

Has anyone tried this?

In whatever capacity I can help, I will do my best to add whatever I can recall as relevant. Thanks again everyone!!! :D :cool:
[Android Head-Units] sciallo:
The one from ft86club is a modified HAL9K, Mainly for looks to fit a specific car. They changed the colors of the built in apps accents from blue to red eliminated a bunch of logos to save space, and had a cache fix for market built right in. The latest HAL9K is right up to date as far as closest to the latest stock available (other than the MCU which is actually still pretty old. I know HAL9K mentioned wanting to keep track of downloads as a reason to leave it on the russian forums before. Really not that much of a pain to register and actually worth following with translation via chrome...
[Android Head-Units] tin2001:
The funny part is mine isn't an S150 either. It was the only specific model name/number I could think of when I wrote it, and I was too tired to bother checking the thread for more.

I'm still not even 100% sure what to call mine - that's part of why I figured we need that identification section so people can confidently say which model they have.

iPod Extension Cable

Does anybody know where I can get an extension cable for the iPod plug on the Ouku? (Connection 21 on the Installation Guide. Round PS2 type plug) Want to run the cable to my center console but it's just a little shorter than I would like to use comfortably.

I've seen iPod dock extension cables that would probably work but I would have to cut a slot instead of a hole to get the cable into the console and I'd rather not do that if I can avoid it.

Thanks.

Edit: Never mind...Found it! What you need to get is an Apple Mac Serial Device Cable ( 8-pin Mini-Din Male/Female Serial Extension Cable ). About $5 on ebay and $6 on Amazon. Hope it helps somebody else that might be looking for the same thing for whatever reason.

I never got around to playing with it yet, too many other projects, I have purchased the unit with the capacitive screen and plan on doing the external mic mod to that so I may not need to play with anything.

How many revisions are there?

Hey guys,

Been reading through this forum for hours, but since Christmas is just around the corner and I need a new toy, I took the plunge on this model:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=151168411354&ssPageName=ADME:L:eek:C:US:3160

It appears that this seller's been linked before and the specs looked fair, but now I'm a bit worried that I might have ordered a pile of poop for Xmas. Not planning on rooting right away so I'm just hoping that it'll will adequately do what it's eBay ad says it should. I'm replacing an old Pioneer AVIC 900BT so I should be easily impressed.

Anyone else here have experience with this specific model?

Thanks,

PMS
[Android Head-Units] sciallo:
It's the android 4.1 version. Hasn't been rooted yet, there is a tread for the 4.1:

http://xdaforums.com/showthread.php?p=47618468#post47618468

The model the OP there has looks different but I think (and that's just my opinion) it's the same with just a different face.
[Android Head-Units] donaldta:
I'm not so sure that it is, [MENTION=1915855]KID52[/MENTION] had indicated that the "AN-21 U" has a ARM Cortex A9 MST786 Dual Core 1GHz and although [MENTION=4836718]PsychoMcSatan[/MENTION]'s winning eBay listing does not show the CPU specs, another listing with the same "face" from the same seller, our_style, seems to indicate that it has a Freescale I.MX535D Cortex A9 Dual-Core CPU. Although, it seems that it may use the similar if not the same System ROM from the radio app screenshots. I'm guessing they were made by different manufacturer but are using the 4.1 source. I wonder if USB Debugging is also password protected on PsychoMcSatan's incoming unit.
[Android Head-Units] PsychoMcSatan:
I think you're right that it's not the same as the 4.1 model in the other thread. Who knows what I'm gonna end up with under the tree this Christmas.

I emailed some questions to the seller (might have been smart to do so before plunking down $400) and I'll post here any info I get.

Thanks,

PMS
[Android Head-Units] G2k0:
Thats odd. Mine came with that cable. Prepared to be disappointed though. The interface kinda sucks (not to mention the app locks up every now and then).
[Android Head-Units] Protius5150:
Sorry...just to clarify...I was looking for an extension cable that I could use to make the cord longer so I could hide the connector in my center console and still have a little length in case I needed it. The unit came with the necessary cable to connect an ipod...I just needed one that was a little longer.

Can i root my extrons th8581ga with The rom in thir thread?

Hi, i tried to read The whole thread, but didnt find any information about this unit

Mi unit specs: capacitive 8gb inand

Cpu information

Freescale I.Mx53

RAM information

512 ddr3 800

Android versión

2.3.7

MCU version

2.11.4-1-10-0101

System version

2.20.21

DVD version

2.13.11-1200wb

I bought it in here:

Alliexpress

But now they offer it with android 4.1 for extra cost, and i payed for this 2.3, because wen i buyed it, they didnt offer that android versión,

Pelase help me with that question, and sorry for. My Bad English, I am from Central América, Guatemala, and if i brick this unit, it will be to hard to send it back, or get another one
[Android Head-Units] sciallo:
That looks like it's exactly the same as the one I have. They now have a 4.1 version out but in my opinion you're better off with yours at this point as there is no root for the 4.1 as of yet and it's not looking too promising on coming up with a root any time too soon. My suggestion is don't update your MCU as there isn't an MCU as new as yours available to flash. I would remove the MCU file alltogether when you flash it. I have tried flashing without updates the system just fine without changing the MCU. I however downgraded mine the first time I flashed it and can't get it back...
[Android Head-Units] guayo65:
Thanks i forgot to say, its the universal head unit, 6.2" with two side knobs and the Cd exposed, and two sd cards slots one for sd and one for gps.

Just to be clear, using the rom from hal9 and flashing the unit doesn't change the MCU?? but does it root the device???

I want to root my unit just for the faster boot time

And my last question, if i flash with this rom, and don't update mcu, is there any chance to get my unit BRICKED???

Thanks for your time
[Android Head-Units] PsychoMcSatan:
I got a response from the eBay seller that my unit's model name is RL257, though that doesn't bring up anything on Google. However, I have found a number of AliExpress units that seem to be identical, or at least they have identical ads.

Some of those ads have comments from mostly Russian buyers so there could be useful info showing up there.

-PMS
[Android Head-Units] sciallo:
Yes, it looks like it's exactly the same unit, here is mine:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=151165193630

The main picture in that listing is sligtly off, it's of a similar one, my unit and I assume yours look exactly like the second picture down (right above "Perfect Panel" and others below it.

Nobody is going to guarrantee 100% you won't brick your unit, as with anything like this there is always a risk.... But I feel damn confident you'll be fine. Even if you did flash the MCU, but I would try leaving your newer MCU there first. There has been ZERO bricked units that I can count on this thread, some scares, but they all got fixed by resets, factory default resets or reflashing. I am the only one still stuck with a non functional unit, negotiating the return with the seller (and at this point feeling that A: I got a defective unit. B: they're "buying time" on the return")

I've been trying to get a copy of the 2.11.4-1-10-0101 MCU from my seller, they sent me a link to update files that are older than the stock ones we can find here. Last time when I asked for return instructions, they told me they would talk to the manufacturer and try to get the newer MCU and two days later (ie. Today) I got this:

I really don't think a local repair shop would know where to start, but I take that as "it's ok to open the unit" so I might see if there is anything obvious going on.

I have been following the russian forums at http://4pda.ru/forum/index.php?showtopic=314557 using translate on chrome. there is a bit of talk on the 4.1 units, they did post a rom for it but I think it's a stock rom, and I thought it was the same exact one as the latest posted on http://xdaforums.com/showthread.php?t=2528349 (and maybe we should keep 4.1 discussions there anyway) that's why I thought they were the same unit with a different face. I only compared the main system file, I will try comparing the whole thing later...

Some of it is really hard to follow with translate, but it seems one of them who had a 2.3 got sent a motherboard to convert to 4.1 I can't really tell if they are any closer to figure out a root for it... Any russian speaking folks in here?
[Android Head-Units] donaldta:
Did you ever get a confirmation if it comes with a Freescale or MST processor?

That's interesting since the 2.3 versions seem to only come with 512MB whereas the 4.1 versions come with 1GB, so it sound like they're getting a nice upgrade. Anyways, I tried to the thread link to the Russian forum but the link does not seem to be valid anymore.
[Android Head-Units] sciallo:
Yes it is indeed interesting, not to mention dual core VS single processor... I couldn't understand if he paid for it or it was some sort of warranty exchange they agreed on or what...

The link is fine, you have to be logged in... Go through the 4pda.ru when you get to the captcha to register (it's an image therefore still in russian) your answer will simpli be the sum of the two numbers you see in there, ignore the cyrillic :)

I went to root my device... I installed the hal9k latest but I forgot not to upgrade the MCU... I went from 2.11.x to 2.10.9 and the sound stopped working. I've tried all images and mcu's I could find but the sound never was restored. I'd like to try 2.11.x but can't find it anywhere... does anyone have it? or has anyone figured out how to fix this (I know others were having the same issues).
[Android Head-Units] G2k0:
Hey guys. Is there a way to re-calibrate the screen after the firmware is applied? It seems that its slightly off (this is for an OUKU // resistive screen)
[Android Head-Units] sciallo:
Oh man... That was me... I guess it's confirmed, downgrading from MCU 2.11.4-1-10-0101 Kills sound. My unit departed back to china today...

So it's official:

Do not downgrade your MCU if you have 2.11.4-1-10

I've been fighting it for a month, the seller sent me a link to an upgrade that was older than hal9k's, tried getting an MCU from the manufacturer unsuccesfully. According to them, the MCU was not the problem (see a few posts above, I pasted their email)...

Drill your supplier for that MCU, if not send it back is all I can suggest.
[Android Head-Units] Shaharov:
Who was the seller out of curiosity.... My seller also sent me "Upgrade files" which I loaded without looking the the MCU... which is what got me here. If the MCU 2.11.x is coming on these systems why can't we get them?
[Android Head-Units] sciallo:
our_style on ebay was my seller. I wouldn't be surprised if it wasn't the same link. The files weren't even named right, only three out of 4 applied without renaming (though system did update) and the MCU was old as hell... I don't know why they couldn't get their hands on the right MCU but (see my quote a few posts ago) they got convinced and sort of convinced me too that the MCU had nothing to do with it.

A while ago I spoke to somebody else here who had a higher MCU to start and didn't have a problem once downgrading, so I was starting to believe the MCU was not at fault. His MCU was 2.11.** as well but still a lower version than my original one. (I would have to go search this or some other forum for the details). Bottom line now we know.... Did you loose sound right after downgrading or did you install other stuff before realizing? The later was the case with me so I wasn't too sure when it happened. The manufacturer will need to cough up those files or they will be getting some back (mine is on the way already) especially if they have sellers sending people the wrong MCU... Sucks to know now that I could have fixed it without spending $60+ to ship it back...

I tried emailing the manufacturer directly, but never got a response from them.

Make a hell of a stink about it until they send you the right MCU!! Then share it so the next one who falls victim of this can fix it too...

everytime i turned on mi headunit, i had to reclibrate the screen, i was installing the capacitive file, then i tried with the resistive, and it worked just fine, i think the seller at aliexpress sent me a resistive instead of capacitive, i will send a bad feedback to this seller, because he offered a capacittive 5 point, and i installed a multitouch program and only registers 1
[Android Head-Units] Shaharov:
Well... I've gotten replies from both the seller and manufacturer. The seller is contacting their tech support and should get back to me in the next day or 2. The manufacturer rep asked for some additional information, which I sent back today. Both responded within 48 hrs so I think that's a good sign. Will keep you updated on what happens.
